We divide 17090329 by 420
We're looking to find how many times 420 goes into 17090329.

Moving on to step 1:
The number 420 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 420

Advancing to step 2:
If we divide 17 by 420, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 420

Going ahead to step 3:
420 goes into 170 0 times with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 170 leaves us with 170.
Append the next digit (9) from the dividend to 170 and continue with: 1709 / 420

On to step 4:
When dividing 1709 by 420, we get 4 with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1680 from 1709, we get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 420

Going ahead to step 5:
420 goes into 290 0 times with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 290, we get 290.
Bring next digit (3) of the dividend behind the 290 and repeat the process: 2903 / 420

Moving on to step 6:
420 goes into 2903 6 times with a remainder of 383.
Write down 6 as next digit of the result. 
Result so far: 406.0
Deduct 2520 from 2903 and we're left with 383.
Fetch the next digit (2) from the dividend, attach it to 383 and continue: 3832 / 420

Moving on to step 7:
420 goes into 3832 9 times with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 4069.0
Deduct 3780 from 3832 and we're left with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 420

Advancing to step 8:
The number 420 fits into 529 1 times, leaving a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 40691.0
Deduct 420 from 529 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
420 goes into 1090 2 times with a remainder of 250.
Record the quotient 2 as the next digit in the result. 
Result so far: 40691.2
If we take 840 away from 1090, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
420 can be fit into 2500 5 times, resulting in a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 40691.25
If we take 2100 away from 2500, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
When dividing 4000 by 420, we get 9 with a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 40691.259
Deduct 3780 from 4000 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
When dividing 2200 by 420, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 40691.2595
The remainder is 100 after subtracting 2100 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
1000 divided by 420 is 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 40691.25952
Subtracting 840 from 1000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
420 goes into 1600 3 times with a remainder of 340.
Record the quotient 3 as the next digit in the result. 
Result so far: 40691.259523
The remainder is 340 after subtracting 1260 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 15:
When dividing 3400 by 420, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 40691.2595238
Subtract 3360 from 3400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
400 divided by 420 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 40691.2595238
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 40691.2595238 with a remainder of 4e-07.
